Definitions

  • the invention relates to a method of capping tire carcasses vulcanized.
  • Today, these processes are generally used in the context of retreading but, of course, everything that will be said below is valid for the trimming of new tire carcasses.
  • retreading process consisting of one, commonly called “cold retreading”, to use a precooked tread that we have on a carcass ready to be retreaded, then to cook the whole in using heating means such as an oven; the other process, called “retreading hot ”, consists in laying a raw tread, in particular in the form of leaves, strips or profile, on a carcass ready to be retreaded and then cooked the whole in a mold.
  • the invention relates to a hot topping process using an annular mold elastic which overcomes these drawbacks.
  • the invention also relates to a topping device which comprises a rim of support for said carcass, an elastic annular mold intended to ensure molding a raw tread covering the tire carcass, and two flexible elastic flanges intended to cover the external surface of the envelope tire thus constituted, comprised between a bead of said envelope and the peripheral edge of the corresponding mold.
  • the choice of radial and axial directions for the retreading device as well as for the tire relates to the axes generally used as reference in the tire, the axial direction corresponding to a direction parallel to the axis of rotation of the tire, the radial planes being planes containing a radius of the tire casing and passing through said axis of rotation.
  • a tire casing to be retreaded 1 comprising a carcass 2 comprising in particular two beads 21, 22 and two sides 23, 24 covered with a raw tread 3, the tread having been deposited on the carcass 2 by any appropriate means, and shoulders 11, 12 connecting the top of the strip of bearing 3 on the sides 23, 24.
  • the retreading device 5 comprises a rim 6 on which the tire 1 must be fitted, an elastic annular mold 7 of molding of the tread 3 and two elastic flanges 8 and 9 intended for cover the outer surface of the tire 1 envelope between a bead 21, 22 of said envelope and the peripheral edge 71, 72 of the mold corresponding in order to seal the tire carcass assembly 2, tread 3, elastic mold 7 and rim 6.
  • the retreading device place on a tire cover is intended to be placed in an enclosure heated and pressurized such as an oven.
  • the elastic mold 7 is in the form of a ring whose inner surface defines the molding of the tread and which has peripheral edges annulars 71, 72 which extend in the form of wings 73, 74 intended to cover the shoulders 11, 12 of the tire 1, respectively.
  • the annular mold 7 must be sufficiently elastic in an oriented direction radially outwards and resist the heat of vulcanization without deforming.
  • the mold must also accept to undergo multiple reheating and resist tearing. We can, for example, use to form this mold annular an elastomer suitable for obtaining the above properties.
  • Such a mold can be produced by way of example in accordance with the method presented.
  • US 3 983 193 in which a tire is used new, as a "molding model", which is covered with a strip of raw vulcanizable rubber.
  • the assembly thus formed is placed in an oven, after being evacuated thanks to a membrane surrounding this assembly, for the purposes to vulcanize the mold.
  • the molding pattern appearing on the surface interior of the mold corresponds to the negative of the tread pattern of the new tire casing used.
  • the mold 7 being extracted from its "molding model", it is necessary to drill in the mold of the vents 75 which extend radially through the thickness of the latter for the future use of the mold in order to allow an evacuation of the air between the mold and the carcass to be retreaded covered with a raw tread during the molding and vulcanization of this tread.
  • the outer circumferential surface of the annular mold 7 is covered with a first elastic draining sleeve 15 allowing the evacuation of air by through the drains, which can be directly deposited on the mold.
  • This sleeve drainant 15 can be secured to mold 7.
  • the sleeve draining 15 is itself covered with an elastic annular membrane 16 based on a vulcanized elastomeric mixture, a non-return valve 17 being integrated into the elastic annular membrane 16 to allow a vacuum to be created.
  • metal inserts 18 can be provided inside the mold distributed along the circumference of the latter and such that all of these inserts form a crown whose sectors are joined in the compressed position of the mold.
  • these inserts can allow the fixing of traction rings 19 in order to facilitate the demolding operations for the cured tire casing.
  • Each elastic flange 8 (9) comprises a peripheral end 81 (91) of small diameter which carries an O-ring seal 30 (31) and a peripheral end of large diameter 82 (92) extended by a second sleeve 83 (93), the diameter is less than the outside diameter of the mold to ensure elastic fixing as well as a pre-sealing of the flanges 8, 9 on the mold 7.
  • the length of this sleeve 83 (93) can be more or less important as will be seen in more detail below.
  • Each flange 8 (9) is made of a waterproof elastic material. We can choose a rubbery material to achieve a good compromise between strength thermal and elasticity.
  • the O-rings 30, 31 cooperate with circumferential housings 62, 63 carried respectively by the heels 60 and 61 of the rim 6.
  • the diameter of the O-rings 30, 31, and therefore the ends of small diameter 81, 91 of the flanges 8 and 9, is less than that of the circumferential housings 62 and 63.
  • the device 5 also includes, as mentioned above, a rim 6 on which the tire carcass is mounted and inflated. Indeed, it is important during the establishment of the elastic mold 7 on the tread that the tire envelope is inflated, on the one hand to ensure resistance to pressure that will be exerted by the mold on the envelope and to have a presentation uniform of the envelope vis-à-vis the mold to facilitate its installation and its centering on the tread.
  • One solution consists in using a rim provided with an inner tube for retreading.
  • the disadvantage of this solution in addition to the fact that it requires the use of a additional membrane constituted by the air chamber, consists in the fact that it is necessary to use a rim whose dimension corresponding to that of the tire of tire to be retreaded, so a rim for each dimension (which is also the case in the use of an ordinary rim for the trimming of a carcass new tire).
  • the Applicant has developed a new rim allowing assembly and disassembly easy of the tire casing without requiring the presence of an inner tube, and which allows the same rim to adapt to tire casings of different dimensions in a given range. So the tire carcass chaper is inflated on this rim by direct action of a fluid on the interior walls of said carcass.
  • the rim 6 comprises a body under shape of a ferrule 64 which carries a fixed heel 61 supporting one of the beads of the tire casing and a movable bead 60 for supporting the other bead.
  • Each heel 61, 60 carries a circumferential housing respectively 63, 62 under form of a groove which extends around the circumference of the heel, which cooperate, as is saw it, with the O-rings 31, 30 carried by the elastic flanges 8, 9.
  • the movable heel 60 is slidably mounted on the ferrule 64 and extractable relative to the latter, the rim 6 also comprising a locking system 35 which keeps the movable heel 60 on the ferrule 64 and limits the spacing maximum between the two heels 60, 61.
  • This locking system 35 is composed of a support washer 36 for the heel mobile 60, itself slidingly mounted on the ferrule 64 and extractable from this last, and an extractable locking crown 37 which is fixed rigidly on the ferrule 64.
  • This crown 37 forms in its “fixed” position a limitation on the ferrule 64 from the position of the movable bead 60 towards the outside of the rim, constituting a stop for the washer 36 on which the movable heel 60 rests, directly or through a spacer 38 'as shown in the variant of the rim in FIGS. 5A and 5B.
  • spacer 38 'as shown in the variant of the rim in FIGS. 5A and 5B.
  • Such spacers allow the rim to be wedged on the nominal distance between rods corresponding to each envelope size of tires and thus authorize the use of the same rim for tires tires of different dimensions for a given range. by a simple change
  • the locking ring 37 carries fingers 39 oriented radially inwards of said crown and which cooperate with the orifices, not shown, in the form of slots pierced in the shell 64. After insertion of the fingers into the orifices, a simple rotation of the crown 37 allows said crown to be axially locked on ferrule 64.
  • the rim 6 ' has a locking ring 37 'which carries an interior surface having recesses delimiting internal circumferential supports 39 ′ which cooperate with recesses carried by the 6 'ferrule and which open onto a circumferential groove retention 67 'so that the rotation of the crown 37' axially locks it on the ferrule 64 '.
  • FIG. 5A illustrates the locked position of the rim 6 ′ in which the rotation of the crown 37 'has been carried out while FIG. 5B shows the relative positions of the ferrule 64 ′ and of the crown 37 ′ in the unlocked position of the 6 'rim.
  • the rim 6 (6 ') also includes a O-ring seal 40 (40 ') whose diameter is less than that of the ferrule 64 (64 ') for sealing and which is put in place by sliding in a housing 600 (600 ') circumferential provided for this purpose and carried by the movable heel 60 (60').
  • the seal 41 (41 ') retains its volume and ensures the sealing or is compressed in its housing 601 (601 '), the same being true for the seal 42 (42 ').
  • the mounting on the rim from this stage allows the use of the same support, rim 6, for all stages of the process.
  • the rim 6 with its axis is positioned on a support vertical, the fixed heel 61 being disposed downwards and the entire movable heel 60 and of the locking system 35 having been removed from the shell 64.
  • the tire carcass 2 is brought with its vertical axis above the rim 6 and said carcass is slid onto the ferrule 64 until the stop of the lower bead of the carcass, the bead 22 according to the figures, on the fixed heel 61.
  • the movable heel 60 so that its surface reception of the bead 21 is oriented towards the tire carcass 2 and is left slide this heel 60, which descends naturally until contact with the bead 21.
  • the O-ring 40 previously greased, is positioned on the one hand, on ferrule 64, and we slide the latter until it comes to put naturally in place in the circumferential housing 600 carried by the movable heel 60, and, on the other hand, the support washer 36 is positioned which abuts on the heel 60 and the seal 40.
  • the locking ring 37 is then presented on the ferrule 64 so that the fingers 39 are vis-à-vis with the housings carried by said ferrule. Following the slide of the crown 37 along the ferrule 64, the fingers 39 come into contact with the bottom slots. Then just turn the crown 37 on the ferrule 64 so that the fingers 39 move this time circumferentially in the slots, which axially locks the crown 37.
  • the rim 6 is locked.
  • the carcass 2 is inflated using the feed 66, which pushes the upper bead 21 which pushes the heel 60 and the support washer 36 up to the contact stop on the crown 37, the O-ring 40 then being compressed between the support washer 36 and the movable heel 60 and ensuring its final tightness.
  • the cured tire casing will also be easily removable from this rim since being positioned again vertically.
  • the upper bead returns to its initial position and releases of any constraint the locking ring 37, which makes it easy to produce unlocking it by rotation and then sliding the rims outwards different extractable elements.
  • the mold 7 being maintained in this stretched position, it is placed inside this last tire cover 1 so that the tread 3 is centered axially with respect to the mold 7.
  • the tensile force exerted on the mold 7 which is compressed on the tread 3.
  • the metal inserts 18 distributed over the circumference of the mold 7 allow to guarantee the thickness of gum which one wishes to keep between the carcass 2 and the background of the sculptures.
  • the sleeve 83 Free from any constraint, the sleeve 83 is folded over the flange 8, the flange being in effect a flexible element.
  • the small diameter peripheral end 81 of the flange 8 is positioned, which carries the O-ring 30.
  • this end 81 is slightly stretched in order to position the O-ring 30 in its housing 63 carried by the heel 61 corresponding, the diameter of the O-ring 30 and therefore of the end 81 being slightly less than that of housing 63.
  • This difference in diameter allows, made of elasticity of the joint and the flange, to ensure the elastic fixing between the flange 8 and heel 61.
  • the flanges 8 and 9 which are paired with the mold 7, do not work under stress important, which is a key difference from the existing system in the prior art and using outer and inner membranes as we have seen previously.
